Control method and device of disaster response unmanned aerial vehicle base stations

Abstract

The embodiment of the invention discloses a control method and device of disaster response unmanned aerial vehicle base stations. The method comprises the following steps: performing rough estimation on the terrain and ground to air channel characteristics of a disaster area, calculating the initial number of unmanned aerial vehicle base stations, and initial positions and initial heights of the unmanned aerial vehicle base stations; deploying the unmanned aerial vehicle base stations according to the initial positions and the initial heights of the unmanned aerial vehicle base stations, and providing network access services for users within the coverage by the unmanned aerial vehicle base stations; periodically measuring, recoding and uploading channel quality information of the users within the coverage of the unmanned aerial vehicle base stations with the unmanned aerial vehicle base stations by the unmanned aerial vehicle base stations; and performing accurate estimation on the terrain and the ground to air channel characteristics of the disaster area by the analysis of the channel quality information, and periodically adjusting the deployment positions and heights of the unmanned aerial vehicle base stations according to the accurate estimation results. By adoption of the control method and device disclosed by the invention, the network communication rate of disaster response communication assisted by the unmanned aerial vehicle base stations can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a control method and device for a base station of a disaster-response UAV. Background technique [0002] Nowadays, mobile phones play a relatively important role in people's daily life. In a mobile communication system, a base station is responsible for uplink data collection and downlink data distribution. When natural disasters such as earthquakes and floods occur, the base station of the mobile communication system may not work normally due to physical damage, or may not work normally due to lack of power supply. At this time, some (rotor) drones carrying base station communication modules can be deployed in disaster-stricken areas where the ground base station of the mobile communication system cannot work normally. UAVs carrying base station communication modules are usually referred to as UAV base stations. UAV base stations provide mobile communication servi...

Problems solved by technology

These methods do not take into account people's behavior after natural disasters, for example, people will choose as high a place as possible to evacuate when a flood occurs, and people will gather in an open square when an earthquake occurs.
